Multivariable Cox regression for mortality risk after 1 year

	Hazard ratio	95% CI for Hazard ratio		P value
	Hazard ratio	Lower	Upper	P value
ASA Score	1.82	1.18	2.8	0.007

A backward stepwise cox regression was used to explore the influence of potential predictors on 1-year mortality in vertebral osteomyelitis out of the following candidate variables: age, native (NVO) vs. vertebral osteomyelitis after spinal injection (SIVO), ASA score and Staphylococcus aureus

NVO native vertebral osteomyelitis, SIVO vertebral osteomyelitis after spinal injection, ASA American Society of Anesthesiologists, CI confidence interval
